Issue Type: Bug

VS Code hangs after running CLS command in the terminal followed by killing all terminal sessions.

1. Create a test.py file, containing print("hello world")
2. Run the file with Ctrl-F5 once: a Python Debug Console terminal will be created.
3. Run cls command in this terminal.
4. Kill the debug terminal by pressing the trash icon. The default cmd terminal will be shown instead.
5. Kill the default terminal by pressing the trash icon again.
6. VS code should now hang indefinitely.
